Performance Index Limits of Medium-Height RC Shear Wall Components
In order to determine the deformation performance index limits for medium-height RC shear wall components based on Chinese codes with the shear span ratio between 1.0 and 2.0, the reliability of the nonlinear finite element method was first verified by four typical medium-height shear wall components experiments in some literatures. Then, the nonlinear finite element method was applied to analyze a set of medium-height RC shear wall components designed according to current Chinese codes. Parametric studies were made of the influence of shear span ratio λ, axial compression ratio μ and main flexural reinforcement ratio of confined boundary members ρflex. Finally, the deformation performance index and its limits of the medium-height RC shear wall components under severe earthquakes are presented by the finite element model results.
